When running fabtest for libfabric I get the following segmentation fault:

The hardware used are two Mellanox Connect-X5 with a back to back connection without a switch. 

Please tell me if you need anything else.

I verified the same behaviour with both libfabric version  1.14.1-1.3 and 1.15.1-74.1
